Communication device

ABSTRACT

A communication device according to the present invention is provided with a message box, a one-touch dial and a private telephone directory. The number of keys for using these functions is minimized in the above communication device. In particular, a box specifying key functions as a key for using the message box, a key for using the one-touch dial and a key for using the private telephone directory.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a communication device provided with a personal information storing device that stores information for a specific individual, which can be input via a telecommunication line.

2. Description of the Related Art

Conventional facsimile terminal equipment is provided with a message box function for storing information for a specific individual in a personal information storing device that is input via a telecommunication line. The personal information storing device can be plural memory areas allocated in a random access memory (RAM) for example. These memory areas are respectively allocated to a different specific individual. Facsimile data or voice data are stored in the corresponding memory area by first specifying the number of a message box in an automatic message recording mode and then sending facsimile or voice via a telephone line from another facsimile terminal or other communication equipment. A specific individual who wants to know the contents of a message addressed to himself/herself can directly operate the facsimile terminal equipment by a predetermined operation, including the input of personal identification numbers, and can retrieve the contents of his/her own message box. The specific individual can also retrieve the contents using another facsimile terminal or other communication equipment, via a telephone line. That is, if data stored in a memory area corresponding to the specific individual's own message box is facsimile data, the data can be printed out on recording paper. If voice data, it can be reproduced from a speaker as voice.

Conventional facsimile terminal equipment are also provided with a one-touch dialing function for automatically calling a telephone number, which a user registers beforehand, by one key operation. This one-touch dialing function is very convenient because a telephone number is automatically called by simply pressing a key corresponding to the desired telephone number that was registered beforehand. The telephone number includes a facsimile number.

Further, conventional facsimile terminal equipment may include a private telephone directory function that displays only telephone numbers or the names of other parties corresponding to the telephone numbers grouped in correspondence with personal information storing devices of plural telephone numbers registered beforehand. The conventional facsimile equipment can then automatically call a telephone number for one of the parties as selected by a user. According to the above private telephone directory function, if a large number of telephone numbers are registered in an abbreviated form, they can be grouped together for every user to whom a message box is allocated. Such a private telephone directory is very convenient for each user to whom a message box is allocated because he/she can utilize it as a telephone directory in which only telephone numbers necessary to himself/herself are registered.

However, because a key for using a message box function, a key for using a touch tone dialing function and a key for using a private telephone directory function are separately provided in the conventional facsimile terminal equipment, there is a problem in that the number of provided keys is increased. If the number of provided keys increases, the facsimile terminal equipment production costs increase because of an increase in the cost of parts and cost of assembling the equipment. An increase in the number of keys also hinders the miniaturization of equipment because of the additional space required for the keys. Further, the additional keys increase the complexity of the equipment, which requires more time for a user to master equipment operations.

SUMMARY OF THE INVENTION

This invention solves the above problem by providing a communication device having a message box function, a one-touch dialing function and a private telephone directory function in which the number of keys required for executing the functions is reduced.

A communication device disclosed in one aspect is provided with a message box function for storing in a personal information storing device information input via a telecommunication line for a specific individual, a one-touch dialing function for automatically calling a telephone number registered beforehand by a user with one key operation and a private telephone directory function for displaying only information corresponding to telephone numbers grouped in correspondence with personal information storing devices of plural telephone numbers registered beforehand and for automatically calling a telephone number selected by the user from the above telephone numbers. The communication device in this aspect is constituted so that at least two of a key for using the above message box function, a key for using the touch tone dialing function and a key for using the private telephone directory function are the same.

According to the above communication device, at least two of a key for using the message box function, a key for using the one-touch dialing function and a key for using the private telephone directory function share a common key. Thus, the number of keys associated with the above three functions can be reduced. Therefore, production costs can be reduced because part's costs and assembling costs can be reduced. Because space required for providing keys can be reduced, miniaturization of the above communication device is enhanced. Further, because the number of keys is reduced, use of the communication device is easier to learn, and operations are streamlined.

A telecommunication line used with the communication device may be a public circuit, a leased line, a wired line or wireless.

For the personal information storing device, volatile memory such as RAM and erasable nonvolatile memory such as EEPROM can be used. However, the personal information storing device is not limited to the above and, for example, a hard disk may be also used. If volatile memory is used, it is desirable that the memory's power supply is backed up by a battery.

The number of provided personal information storing devices is arbitrary. However, if plural devices are provided, specification information for specifying personal information storing means is required to be input.

For the communication device, facsimile terminal equipment or a telephone set can be used. However, the communication device is not limited to the above and, for example, a personal computer, a word processor, and an electronic printer that has a voice function and a facsimile sending/receiving function can be used.

For a key, a pushbutton switch may be used. However, the key is not limited to the above pushbutton switch and a touch-sensitive switch may be also used. Further, switching can be executed by directly touching an icon on a display screen or by moving a cursor onto the icon on the display screen and clicking a mouse.

Registration of a telephone number can be executed by storing the telephone number in nonvolatile memory such an EEPROM. A telephone number may be also stored in a volatile memory such as a RAM and may be also stored in a hard disk.

For displaying information corresponding to grouped telephone numbers, the telephone number and a name corresponding to a telephone number may be also displayed.

A communication device disclosed in a second aspect is based on the communication device according to the first aspect constituted so that a common key functions as the key for using the message box function, the key for using the touch tone dialing function and the key for using the private telephone directory function. If the common key is pressed during a call, it functions as the key for using the message box function. If the common key is pressed together with a first predetermined key except the common key, the common key functions as the key for using the private telephone directory function. If the common key is independently pressed, it functions as the key for using the touch tone dialing function.

In the above communication device, because the common key functions as the key for using the message box function, the key for using the touch tone dialing function and the key for using the private telephone directory function, in addition to effect produced by the communication device according to the first aspect, the number of provided keys can be reduced to the minimum.

In this aspect of the communication device, the first predetermined key may be a single key or may be multiple keys.

A communication device disclosed in a third aspect is based on the communication device according to the preceding aspect and is further constituted so that if the above common key is pressed in conjunction with a second predetermined key, except the first predetermined key, the common key functions as the key for using the message box function.

According to the above communication device, the message box function can be used on standby in addition to the effect produced by the communication device according to the second aspect.

The second predetermined key may be a single key or may be multiple keys.

A communication device disclosed in a fourth aspect is based on the communication device according to the first to the third aspects and is constituted so that if the above common key functions as the key for using the message box function, the message box function is enabled by pressing a key, except for the common key, for inputting password information. The password key is registered beforehand and corresponds to a message box.

In the above communication device, because the message box function is enabled by pressing the key for inputting password information registered beforehand corresponding to a message box, in addition to effect produced by the communication device according to the first to the third aspects, unauthorized use of the message box can be prevented.

For password information, predetermined digits of numeric character, input by a user pressing plural dial keys in a predetermined order, for example, can be used.

A communication device disclosed in a fifth aspect is based on the communication device according to the first to the fourth aspects and is constituted so that if the above common key functions as the key for using the private telephone directory function, the private telephone directory function is enabled by pressing a key, except the common key, for inputting password information registered beforehand and corresponding to a private telephone directory.

According to the above communication device, because the private telephone directory function is enabled by pressing the key for inputting password information registered beforehand and corresponding to the private telephone directory, in addition to the effect produced by the communication device according to the first to the fourth aspects, the private telephone directory cannot be used by a person who does not know the password information.

The password information of the private telephone directory may also be the same as that of the message box.

A communication device disclosed in a sixth aspect is based on the communication device according to the first to the fifth aspects and is constituted so that, in referring to the private telephone directory function, when the user selects an abbreviated number for each telephone number in the group by pressing dial keys equivalent to the above selected abbreviated number, the telephone number is automatically called and the telephone number corresponding to the displayed name or the displayed telephone number is automatically called by displaying a name corresponding to each telephone number or the telephone number in the group in a predetermined order when a user first presses a third predetermined key and then presses a fourth predetermined key different from the third predetermined key.

Both the abbreviated dial function of the private telephone directory and the function for retrieving the names in alphabetical order can be utilized in addition to effect produced by the communication device according to the first to the fifth aspects. Thus, the above communication device is very convenient.

FIG. 4 is a schematic drawing showing storage areas in the RAM 3. In the RAM 3, a personal information storage area, a general information storage area and a response message storage area are set. In addition, an arbitrary number of areas for storing voice data and facsimile data, which can be freely retrieved from another communication terminal, may be set in the RAM 3, and voice data and facsimile data for advertisement may be also stored beforehand in one of the arbitrary number of areas. In this embodiment, five personal information storage areas are set. A predetermined capacity of the voice data storage area and a predetermined capacity of the facsimile data storage area are respectively set for each personal information storage area. The storage capacity of the above each personal information storage area, each voice data storage area and each facsimile data storage area is not individually determined. Instead, the whole personal information storage area is only limited to predetermined capacity, thereby providing flexible memory control in which storage capacity can be freely secured in the order of arrival of messages. The storage capacity of each voice data storage area and each facsimile data storage area may also be individually fixed. These personal information storage areas are allocated to each specific individual and are used as a message box. That is, voice data or facsimile data sent from another communication terminal, by specifying a message box number, is stored in the corresponding personal information storage area. The voice data and facsimile data are set so that the stored voice data or facsimile data cannot be retrieved unless password information, which only a specific individual who is the owner of the personal information storage area knows, is input. On the other hand, in the general information storage area, the predetermined number of voice data storage areas and facsimile data storage areas are provided, and in an automatic message recording mode, voice data and facsimile data can be freely input from another communication terminal to the general information storage areas without specifying a message box number. In addition, the contents can be freely extracted without inputting password information. When facsimile receiving is set to memory receiving, facsimile data can also be freely input from another communication terminal. In this embodiment, the general information storage area is called a general mail box. The response message storage area stores voice data for outputting various voice response messages.

Thus, the personal information storage area in the RAM 3 constitutes the personal information storage device for storing information input via the telephone line 21 for a specific individual. Each box specifying key 23 constitutes a common key, which functions as a key for using a message box function, a key for using a touch tone dialing function and a key for using a private telephone directory function.

Next, the outline of the operation of the facsimile terminal equipment will be described. The facsimile terminal equipment can access each message box in an automatic message recording mode. When a user hears a ringing tone and lifts a handset in a manual receiving mode, for example, or when a user presses the speaker phone key 42 in a manual receiving mode, for example, voice information or facsimile information input via the telephone line 21 can be stored in the personal information storage area in the RAM 3. Voice information or facsimile information can also be retrieved from the personal information storage area in the RAM 3 via the telephone line 21 by inputting a dual tone multiple frequency (DTMF) signal via the telephone line 21. The voice information or the facsimile information is retrieved using a predetermined operation of the operating section 13 by a user or by a predetermined operation by a caller. If voice information or facsimile information is retrieved from the personal information storage area in the RAM 3 via the telephone line 21, a pre-registered password corresponding to each personal information storage area is required to be input as the DTMF signal to prevent unauthorized retrieval.

As an example of the above process, when Mr. A calls facsimile terminal equipment belonging to Mr. B to input a message to Mr. B's message box, the desired message can be stored in Mr. B's message box without hanging up the call in one of at least two ways. First, Mr. A asks Mr. C to execute a predetermined operation (described below) so as to input a message to the message box. Second, Mr. A sends a predetermined DTMF signal by operating Mr. A's facsimile terminal equipment even if Mr. B's facsimile terminal equipment is not set to an automatic message recording mode and Mr. C answers the call. The message may be voice or an image such as a character.

Referring to the above predetermined operation for the operating section 13 by Mr. C, Mr. C first presses the private key 29, next presses the key of "B" corresponding to Mr. B's message box of box specifying keys 23 and finally presses the recording key 24. As a result, the speaker of the handset is turned off, the telephone line 21 is not released even if Mr. C puts the handset on hook, and a facsimile signal or a voice signal input from Mr. A's facsimile terminal equipment via the telephone line 21 is stored in a personal information storage area in the RAM 3 corresponding to Mr. B's message box as facsimile data or voice data.

Mr. A may also operate the facsimile terminal equipment on the calling side in place of the predetermined operation by Mr. C. That is, when Mr. A presses dial keys in the order of [0], [2] and [*], a DTMF signal corresponding to the pressed dial keys is input to the above facsimile terminal equipment via the telephone line 21 and the facsimile terminal equipment is placed in the same state as when Mr. C executes the above predetermined operation. Dial key [2] of the above dial keys [0], [2] and [*] denotes Mr. B's message box. As described above, Mr. A himself can store a message in Mr. B's message box even if Mr. C does not know the predetermined operation.

When Mr. D calls the above facsimile terminal equipment to retrieve the contents of his own message box at his destination, he can retrieve the contents of his own message box without hanging up the call in one of at least two ways. First, Mr. D can ask Mr. E. to execute a predetermined operation so as to output the message from Mr. D's message box. Second, Mr. D can himself send a predetermined DTMF signal to operate facsimile terminal equipment at the destination even if the original facsimile terminal equipment is not set to an automatic message recording mode and Mr. E answers the call. If the above message is a voice message, Mr. D can listen to it from the speaker of the handset of the facsimile terminal equipment at the destination. If the above message is an image message, the image message can be printed on recording paper by the facsimile terminal equipment at the destination and can be displayed on the display screen.

Referring to the predetermined operation for the operating section 13 by Mr. E, Mr. E first presses the private key 29, next presses the key of "D" corresponding to Mr. D's message box of the box specifying keys 23 and finally presses the reproduction key 26. Mr. D inputs his own personal identification numbers (i.e., password information) by operating dial keys of the facsimile terminal equipment at the destination in a predetermined time. Mr. D's personal identification numbers are input to the above facsimile terminal equipment as a DTMF signal from the facsimile terminal equipment on the calling side via the telephone line 21. As a result, the speaker of the handset is turned off, the telephone line 21 is not released even if Mr. E puts the handset on hook, and facsimile data or voice data stored in the personal information storage area in the RAM 3 corresponding to Mr. D's message box is output as a facsimile signal or a voice signal via the telephone line 21.

Mr. D may also operate the facsimile terminal equipment on the calling side in place of the predetermined operation by Mr. E. That is, a DTMF signal corresponding to pressed dial keys is input to the above facsimile terminal equipment via the telephone line 21 when Mr. D presses dial keys in the order of [0], [4] and [*] and the facsimile terminal equipment is placed in the same state as when the above predetermined operation is executed by Mr. E. At this time, Mr. D is also required to input his own personal identification numbers. Key [4] of the above dial keys [0], [4] and [*] denotes Mr. D's message box.

The above facsimile terminal equipment can also access a general mail box in an automatic message recording mode. When a user hears a ringing tone and lifts a handset in a manual receiving mode, for example, or when a user presses the speaker phone key 42 in a manual receiving mode for example, voice information or facsimile information input via the telephone line 21 can be stored in the general information storage area in the RAM 3. Further, voice information or facsimile information can be retrieved from the general information storage area in the RAM 3 via the telephone line 21. Retrieval occurs by inputting a DTMF signal via the telephone line 21 using a predetermined operation of the operating section 13 by a user or a predetermined operation by a caller.

For example, when Mr. A calls the above facsimile terminal equipment to input a message to a general mail box, a desired message can be stored in the general mail box without hanging up the call by asking Mr. C to execute a predetermined operation so as to input the message to the general mail box. Alternatively, Mr. A can send a predetermined DTMF signal using Mr. A's operating facsimile terminal equipment even if the above facsimile terminal equipment is not set to an automatic message recording mode and Mr. C answers the call. The above message may be voice or an image such as a character.

Referring to the predetermined operation for the operating section 13 by Mr. C, for example, Mr. C presses the private key 29 and next presses the recording key 24. As a result, the telephone line 21 is not released even if Mr. C puts the handset on hook, and a facsimile signal or a voice signal input from Mr. A's facsimile terminal equipment via the telephone line 21 is stored as facsimile data or voice data in the general information storage area in the RAM 3 corresponding to the general mail box.

Mr. A may also operate the facsimile terminal equipment on the calling side in place of the predetermined operation by Mr. C. For example, a DTMF signal corresponding to the pressed dial keys is input to the above facsimile terminal equipment via the telephone line 21 when Mr. A presses dial keys in the order of [0] and [*] and the facsimile terminal equipment is placed in the same state as when the above predetermined operation is executed by Mr. C.

When Mr. D calls the above facsimile terminal equipment to retrieve the contents of the general mail box at his destination, he can retrieve the contents of the general mail box without hanging up the call in one of at least two ways. First, Mr. D asks Mr. E to execute a predetermined operation so as to output messages from the general mail box. Secondly, Mr. D sends a predetermined DTMF signal to operate facsimile terminal equipment at the destination even if the original facsimile terminal equipment is not set to an automatic message recording mode and Mr. E answers the call. If the above message is a voice message, Mr. D can listen to it from the speaker of the handset of the facsimile terminal equipment at the destination. If the above message is an image message, the image message can be printed on recording paper and can be displayed on the display screen respectively by the facsimile terminal equipment at the destination.

Referring to the predetermined operation of the operating section 13 by Mr. E, for example, Mr. E presses the private key 29 and next presses the reproduction key 26. As a result, the telephone line 21 is not released even if Mr. E puts the handset on hook. Facsimile data or voice data stored in the general information storage area in the RAM 3 corresponding to the general mail box are output as a facsimile signal or a voice signal via the telephone line 21.

Mr. D may also operate the facsimile terminal equipment on the calling side in place of the predetermined operation by Mr. E. That is, a DTMF signal corresponding to pressed dial keys is input to the above facsimile terminal equipment via the telephone line 21 when Mr. D presses dial keys in the order of [0] and [*] and the facsimile terminal equipment is placed in the same state as when the above predetermined operation is executed by Mr. E.

As described above, access to a general mail box is enabled by the same operation as an operation for access to a message box except that no operation to specify the number of the message box is executed.

The above facsimile terminal equipment is provided with a telephone directory function for automatically calling by retrieving or specifying any of the telephone numbers of plural desired parties registered beforehand together with the names of the parties. In this operation, the box specifying key 23 is also used as a key for touch tone dialing. That is, each telephone number for touch tone dialing is registered for five box specifying keys 23 and a telephone number corresponding to a pressed box specifying key 23 is automatically called only by selecting any box specifying key 23 and pressing it once.

Further, in the above facsimile terminal equipment, a group name for every box specifying key 23 can be registered in a telephone directory and the registered telephone directory can be used as a private telephone directory for every group. That is, if "A" of the box specifying keys 23 is allocated to Mr. A, a group name "A" is registered in the telephone directory. Then, when Mr. A uses his own private telephone directory, only telephone numbers for which the group name A is registered can be displayed and specified. To use the private telephone directory, Mr. A first presses the private key 29 on standby, next presses "A" of the box specifying keys 23 and next presses dial keys 22 corresponding to Mr. A's personal identification number. As a result, Mr. A's private telephone directory is enabled. Then, when Mr. A presses dial keys 22 corresponding to two digits of an abbreviated telephone number registered beforehand, the name of the corresponding party is displayed on the LCD 45 display screen. At this time, if a handset is off hook, the telephone number corresponding to the name of the party displayed on the LCD 45 display screen is automatically called. If a handset is on hook, the telephone number corresponding to the name of the party displayed on the LCD 45 display screen is automatically called by pressing the start key 33. When "A" of the box specifying keys 23 or the scroll keys 36 and 38 are pressed in order, the names of parties in Mr. A's private telephone directory are sequentially displayed on the LCD 45 display screen in alphabetical order. When the name of a desired party is displayed on the LCD 45 display screen, the telephone number corresponding to the displayed name of the party is automatically called by pressing the start key 33. The telephone number of the party may be also displayed on the LCD 45 display screen in place of the name.

Next, referring to flowcharts shown in FIGS. 5 to 10, the procedure of receiving processing in each operation mode by the above facsimile terminal equipment will be described.

In the automatic message recording mode, as shown in FIG. 5, the CPU 1 judges whether the facsimile terminal equipment is called (S1).

If the facsimile terminal equipment is called (S1: YES), the CPU 1 closes a line by controlling the NCU 2 and makes the facsimile terminal equipment receive (S2). At this time, if a message box is set on, nonringing receiving, in which a calling bell is not rung, is executed independent of the set frequency of a calling bell. If the message box is set off, ringing receiving, in which a calling bell is rung according to its set frequency, is executed. The calling bell is also output from the speaker 66 of the accessory handset 16. When the message box is set off, access to the message box is disabled. Next, the CPU 1 starts a timer (S3). The timer determines the time to detect whether a CNG signal showing facsimile sending is sent from a calling terminal and for example, is set to four seconds. Next, the CPU 1 judges whether the CNG signal is detected (S4). That is, the CPU checks whether the CNG signal is input via the telephone line 21.

Next, the CPU 1 judges whether the CNG signal is detected (S4). That is, the CPU 1 checks whether the CNG signal is input via the telephone line 21.

If the CNG signal is not detected (S4: NO), the CPU 1 judges whether time measured by the timer started in S3 is up (S5).

If the time is up (S5: YES), the CPU 1 judges that the incoming message is not a facsimile because the CNG signal is not input in a predetermined time. The CPU 1 then starts the reproduction of a guidance message for the F/T mode (S6). That is, the CPU 1 reads voice data corresponding to the guidance message for the F/T mode from the response message storage area in the RAM 3. The CODEC 8 converts the voice data to an aural signal. Then the CPU 1 sends the aural signal to the telephone line 21 via the NCU 2. Next, the CPU 1 judges whether the CNG signal is detected (S7).

If the CNG signal is not detected (S7: NO), the CPU 1 judges whether a message box number is specified (S8). That is, because the DTMF signal corresponding to pressed dial keys is input via the telephone line 21 when the dial keys are pressed to specify the message box number on the side of the calling terminal, the CPU 1 judges whether the DTMF signal is input. The box specifying keys 23 (A to E) of the above facsimile terminal equipment respectively correspond to each message box. The message boxes respectively correspond to the dial keys 1 to 5 of the calling terminal, for example. Therefore, the desired message box is specified by pressing any of the dial keys 1 to 5 in place of pressing any of the box specifying keys 23 (A to E). For example, the dial keys of the calling terminal are pressed in the order of [0], [1] and [*] in place of the box specifying key 23 (A).

If a box number is not specified (S8: NO), the CPU 1 judges whether the reproduction started in S6 of the guidance message for the F/T mode is finished (S9).

If the reproduction of the guidance message for the automatic message recording mode is finished (S9: YES), the CPU 1 judges that the type of an incoming message is a message of general voice information, not addressed to a specific individual, because the CNG signal is not detected and in addition, no number of a message box is specified during the reproduction of the guidance message for the automatic message recording mode. The CPU 1 then records the incoming message in general information storage area (S10). In operation, the CPU 1 converts an aural signal input via the telephone line 21 to digital voice data using the CODEC 8 and stores the voice data in a voice data storage area of any general information storage area in the RAM 3. The CPU 1 always judges during the reproduction of the guidance message for the automatic message recording mode, whether the CNG signal and the DTMF signal for specifying a message box number are detected. That is, because a period for reproducing the guidance message for the automatic message recording mode normally includes the time in which the guidance message is actually sent and the time following without a sound, the CPU 1 checks whether the CNG signal or the DTMF signal is detected during the period. Next, the CPU 1 judges whether recording of the incoming message in the general information storage area is finished (S11).

If recording of the incoming message in the general information storage area is finished (S11: YES), the CPU 1 disconnects the line (S12) and terminates the routine.

In S11, if recording of the incoming message in the general information storage area is not finished (S11: NO), processing returns to S10 and recording of the incoming message continues.

In S9, if the reproduction of the guidance message for the automatic message recording mode is not finished (S9: NO), processing returns to S6 and the reproduction of the guidance message for the automatic message recording mode continues.

In S8, if the box number is specified (S8: YES), the CPU 1 executes message box processing (S14) because the above means that the message is a message addressed to a specific individual. The CPU 1 then terminates the routine. The above message box processing will be described later in detail.

In S7, if the CNG signal is detected (S7: YES), the CPU 1 executes general facsimile receiving because the above means facsimile receiving that is not addressed to a specific individual (S15). In S15, the CPU 1 stores facsimile data received via the telephone line 21 in a facsimile data storage area of any general information storage area in the RAM 3. Next, the CPU 1 judges whether the general facsimile receiving is finished (S16).

If the general facsimile receiving is finished (S16: YES), the CPU 1 disconnects the line (S17) and judges whether transfer is set on (S18).

If transfer is set on (S18: YES), the CPU 1 calls a communication terminal of a transfer destination (S19) and sends the facsimile data received in S15 (S20). That is, as in the automatic message recording mode, received facsimile data is stored in a facsimile data storage area of any general information storage area in the RAM 3, the CPU 1 transfers the facsimile data to a communication terminal of a telephone number registered beforehand. Transfer is set on or off and a telephone number is registered beforehand by a user pressing a predetermined key, such as the function key 28.

Next, the CPU 1 judges whether the transfer is finished (S21). If transfer is finished (S21: YES), the CPU 1 makes processing proceed to S12, disconnects the line and terminates the routine.

In S21, if the transfer is not finished (S21: NO), processing returns to S20 and the transfer continues.

In S18, if transfer is not set on (S18: NO), the routine is terminated because no transfer is required.

In S16, if the general facsimile receiving is not finished (S16: NO), processing returns to S15 and the general facsimile receiving continues.

In S5, if time measured by the timer started in S3 is not up (S5: NO), processing returns to S4 and the detection of the CNG signal continues.

In S4, if the CNG signal is detected (S4: YES), processing proceeds to S15 because the above means that facsimile data is automatically sent by a calling terminal and processing after the general facsimile receiving is executed.

In S1, if the facsimile terminal equipment is not called (S1: NO), the routine is finished.

Next, the procedure of the message box processing shown in S14 in FIG. 5 will be described. In the message box processing, as shown in FIG. 6, the CPU 1 starts the reproduction of a guidance message for a message box specified by a DTMF signal (S31). That is, the CPU 1 reads voice data corresponding to the guidance message for the specified message box from the response message storage area in the RAM 3, converts it to an aural signal by the CODEC 8 and sends the aural signal to a calling terminal via the telephone line 21. During this time, no sound is output from the speakers including the speaker of the handset provided with the body, the speaker provided with the body except the handset and the speaker 66 of the accessory handset 16. Next, the CPU 1 judges whether the CNG signal is detected (S32). That is, the CPU 1 checks whether the CNG signal is received via the telephone line 21.

If the CNG signal is not detected (S32: NO), the CPU 1 judges whether a password is specified (S33). That is, the CPU 1 checks whether personal identification numbers corresponding to the specified message box are correctly input as a DTMF signal. This check is executed to prevent a person who does not know the personal identification numbers from retrieving the contents of the message box. If no password is specified (S33: NO), the CPU 1 judges whether the reproduction of the guidance message for the message box specified by the DTMF signal is finished (S34).

If the reproduction of the guidance message for the message box specified by the DTMF signal is finished (S34: YES), the CPU 1 judges the input to be a voice message to the message box because the above means that no CNG signal and no DTMF signal corresponding to the personal identification numbers are input during the reproduction of the guidance message. The CPU 1 then starts recording the incoming message in the information storage area of the specified message box (S35). Specifically, the CPU 1 makes the CODEC 8 convert an aural signal input via the telephone line 21 to digital voice data and stores the voice data in a voice data storage area in a personal information storage area corresponding to the specified message box in the RAM 3. Next, the CPU 1 judges whether recording of the incoming message in the information storage area is finished (S36).

If recording of the incoming message in the information storage area is finished (S36: YES), the CPU 1 judges whether facsimile data is received (S37).

If facsimile data is received (S37: YES), the CPU 1 stores the received facsimile data in the specified message box (S38). Specifically, the modem 4 demodulates a received facsimile signal. The CPU 1 then stores the demodulated facsimile data in the facsimile data storage area in the personal information storage area corresponding to the specified message box in the RAM 3. Next, the CPU 1 judges whether the receiving of the facsimile data is finished (S39).

If the receiving of the facsimile data is finished (S39: YES), the CPU 1 disconnects the line (S40). If individual paging is set on, the CPU 1 calls the individual paging number (S41) and terminates the routine. If individual paging is set off, the individual paging number is not called and the routine terminates. The above individual paging number is the telephone number of a communication terminal, which is to be informed via the telephone line 21 that a message is input in a message box. One or plural individual paging numbers are set for every message box. If a message is input in a message box, the CPU 1 calls the above telephone number and automatically provides an indication that the message exists. For example, a character is displayed on the display screen of a pager, facsimile terminal equipment, or a telephone set, which are communication terminals, to indicate that a message is input in a message box. In addition to reporting that a message is input in a message box, the message input in the message box itself may also be sent if the communication terminal of a sending destination is capable of receiving messages. For example, if a communication terminal of a sending destination is a pager or a telephone set not provided with a function for receiving facsimile data, a facsimile message cannot be sent.

In S39, if the receiving of facsimile data is not finished (S39: NO), processing returns to S38 and the receiving of the facsimile data continues.

In S37, if facsimile data is not received (S37: NO), processing proceeds to S40 because facsimile data is not required to be stored in a message box and processing after the disconnection of the line is executed.

In S36, if recording of the incoming message in the personal information storage area is not finished (S36: NO), processing is returned to S35 and recording of the incoming message continues.

In S34, if the reproduction of the guidance message for the message box specified by the DTMF signal is not finished (S34: NO), processing returns to S31 and the reproduction of the guidance message continues.

In S33, if a password is specified (S33: YES), that is, if the DTMF signal corresponding to the personal identification number of the specified message box is input, the CPU 1 reproduces the contents of the personal information storage area of the specified message box (S42). Specifically, the CODEC 8 converts voice data stored in the voice data storage area of the personal information storage area corresponding to the specified message box in the RAM 3 to an analog aural signal. The CPU 1 then sends the aural signal to the telephone line 21 via the NCU 2. Next, the CPU 1 judges whether reproducing the contents of the personal information storage area of the specified message box is finished (S43).

If reproducing the contents of the personal information storage area of the specified message box is finished (S43: YES), the CPU 1 reproduces a guidance message for general retrieval (S44). Specifically, the CPU 1 reads voice data corresponding to the guidance message for general retrieval stored in the response message storage area in the RAM 3. The CODEC 8 converts the voice data to an analog aural signal. The CPU 1 then sends the aural signal to the telephone line 21 via the NCU 2. The above operation is executed to check whether a user of a calling terminal wants to retrieve not only a message stored in a message box but also a message stored in the general mail box not addressed to a specific individual. Next, the CPU 1 judges whether a DTMF signal showing that general retrieval is required is input (S45).

If a DTMF signal showing that general retrieval is required is input in the predetermined time since the start of reproducing the guidance message for general retrieval (S45: YES), the CPU 1 sets a flag F to "1" (S46) and starts to reproduce the contents of general information storage area (S47). specifically, the CPU 1 reads voice data stored in a voice data storage area of any general information storage area in the RAM 3. The CODEC 8 converts the voice data to an analog aural signal. Then the CPU 1 sends the aural signal to the telephone line 21 via the NCU 2. As described above, reading data stored in a general information storage area is called general retrieval. Next, the CPU 1 judges whether the reproduction of the contents of the general information storage area is finished (S48).

If the reproduction of the contents of the general information storage area is finished (S48: YES), the CPU 1 outputs a sound for reporting on a facsimile message. First, the CPU 1 reads voice data, corresponding to a report message stored in the response message storage area in the RAM 3, that facsimile data will be sent. Then the CODEC 8 converts the voice data to an analog aural signal. Finally, the CPU 1 sends the aural signal to the telephone line 21 via the NCU 2. In this way, a user of a calling terminal starts facsimile receiving by pressing the start key of the calling terminal.

Next, the CPU 1 reproduces the contents of the specified message box in the form of facsimile data (S50). First, the modem 4 modulates facsimile data stored in a facsimile data storage area in a personal information storage area corresponding to the specified message box in the RAM 3. Then the CPU 1 sends the facsimile signal to the telephone line 21 via the NCU 2. Next, the CPU 1 judges whether reproducing the contents of the specified message box in the form of facsimile data is finished (S51).

If reproducing the contents of the specified message box in the form of facsimile data is finished (S51: YES), the CPU 1 judges whether the flag F is "1" (S52).

If the flag F is set to "1" (S52: YES), the CPU 1 starts the reproduction of the contents of the general mail box in the form of facsimile data because the above means that a request for retrieving the contents of the general mail box, not addressed to a specific individual, is made from a calling terminal (S53). First, the CPU 1 reads facsimile data stored in a facsimile data storage area in any general information storage area in the RAM 3. Then the modem 4 modulates the facsimile data and sends the facsimile data to the telephone line 21 via the NCU 2. Next, the CPU 1 judges whether the reproduction of the contents of the general mail box in the form of facsimile data is finished (S54).

If the reproduction of the contents of the general mail box in the form of facsimile data is finished (S54: YES), the CPU 1 sets the flag F to "0" (S55), disconnects the line (S56) and terminates the routine.

In S54, if the reproduction of the contents of the general mail box in the form of facsimile data is not finished (S54: NO), processing returns to S53 and the reproduction of the contents of the general mail box in the form of facsimile data continues.

In S52, if the flag F is not set to "1" (S52: NO), the contents of the general mail box in the form of facsimile data is not reproduced. Then, processing proceeds to S56 because the above means that a request for retrieving the contents of the general mail box, not addressed to a specific individual, is not made from the calling terminal.

In S51, if the reproduction of the contents of the specified message box in the form of facsimile data is not finished (S51: NO), processing returns to S50 and the reproduction of the contents of the specified message box in the form of facsimile data continues.

In S48, if the reproduction of the contents of the general personal information storage area is not finished (S48: NO), processing returns to S47 and the reproduction of the contents of the general personal information storage area continues.

In S45, if the DTMF signal requiring general retrieval in the predetermined time since the start of the reproduction of the guidance message for general retrieval is not input (S45: NO), the CPU 1 sets the flag F to "0" (S57) and processing proceeds to S49 without reproducing the contents of the general personal information storage area.

In S43, if reproducing the contents of personal information storage area of the specified message box is not finished (S43: NO), processing returns to S42 and reproducing the contents of personal information storage area of the specified message box continues.

In S32, if the CNG signal is detected (S32: YES), processing proceeds to S38 without recording in the personal information storage area because the above means that a user of a calling terminal wants to leave only a facsimile message in the specified message box.

Next, receiving processing in an automatic switching mode between a facsimile and a telephone (hereafter F/T) mode will be described. In the F/T mode, as shown in FIG. 7, the CPU 1 judges whether the facsimile terminal equipment is called (S61).

If the above equipment is called (S61: YES), the CPU 1 controls the NCU 2 to close a line and receive messages (S62). At this time, if the message box is set on, nonringing receiving, in which no calling bell is rung, is executed independently of a set frequency of the calling bell. If the message box is set off, ringing receiving, in which the calling bell is rung according to the set frequency of the calling bell, is executed. The calling bell is also output from the speaker 66 of the accessory handset 16. Next, the CPU 1 starts a timer (S63). The timer sets the time to detect the CNG signal from the calling terminal. For example, the time is set to four seconds. Next, the CPU 1 judges whether the CNG signal is detected (S64). That is, the CPU 1 checks whether the CNG signal is input via the telephone line 21.

If the CNG signal is not detected (S64: NO), the CPU 1 judges whether time measured by the timer started in S63 is up (S65).

If the time is up (S65: YES), the CPU 1 judges that the incoming message is not a facsimile because the CNG signal is not input in a predetermined time. The CPU 1 then starts the reproduction of a guidance message for the F/T mode (S66). That is, the CPU 1 reads voice data corresponding to the guidance message for the F/T mode from the response message storage area in the RAM 3. The CODEC 8 converts the voice data to an aural signal. Then the CPU 1 sends the aural signal to the telephone line 21 via the NCU 2. Next, the CPU 1 judges whether the CNG signal is detected (S67).

If the CNG signal is not detected (S67: NO), the CPU 1 judges whether a box number is specified (S68). That is, because the DTMF signal corresponding to pressed dial keys is input via the telephone line 21 when the dial keys are pressed to specify the message box number on the side of the calling terminal, the CPU 1 judges whether the DTMF signal is input. The box specifying keys 23 (A to E) of the above facsimile terminal equipment correspond to each message box. The message boxes correspond to the dial keys 1 to 5 of the calling terminal, for example. Therefore, the desired message box is specified on the side of the calling terminal by pressing any of the dial keys 1 to 5 in place of pressing any of the box specifying keys 23 (A to E). For example, the dial keys of the calling terminal are pressed in the order of [0], [1] and [*] in place of the box specifying key 23 (A).

If a box number is not specified (S68: NO), the CPU 1 judges whether the reproduction started in S66 of the guidance message for the F/T mode is finished (S69).

If the reproduction of the guidance message for the F/T mode is finished (S69: YES), the CPU 1 starts a second timer (S70) and judges whether time measured by the second timer is up (S71). The second timer is different from the timer started in S63, in that it affords the user of the calling terminal time for specifying the message box number after the reproduction of the guidance message for F/T mode is finished. For example, time measured by the second timer is up in two seconds.

If time measured by the second timer started in S70 is up (S71: YES), the CPU 1 rings the calling bell (S72). When the user, in response to the calling bell, lifts the handset, presses the speaker phone key 42 or presses the outside line key 52 of the accessory handset 16, conversation is enabled (S73). When the conversation is finished, the CPU 1 disconnects the line (S74) and terminates the routine.

In S71, if time measured by the second timer started in S70 is not up (S71: NO), the CPU 1 judges whether the box number is specified (S75). If the box number is specified (S75: YES), processing proceeds to S75 to execute message box processing. If the box number is not specified (S75: NO), processing returns to S71 to wait until the box number is specified or the time measured by the timer is up.

In S69, if the reproduction of the guidance message for the F/T mode is not finished (S69: NO), processing returns to S66 and the reproduction of the guidance message for the F/T mode continues.

In S68, if the box number is specified (S68: YES), the CPU 1 executes message box processing (S78) because the above means that the message is addressed to a specific individual the CPU 1 then terminates the routine. The above message box processing is the same as that shown in FIG. 6.

In S67, if the CNG signal is detected (S67: YES), the CPU 1 executes general facsimile receiving (S76) because the above means that facsimile not addressed to a specific individual is received. When the CPU 1 executes general facsimile receiving (S76), if memory receiving is set, facsimile data received via the telephone line 21 is stored in the facsimile data storage area in any general information storage area in the RAM 3. If memory receiving is not set, facsimile data received via the telephone line 21 is recorded on recording paper by the recording section 12. Next, the CPU 1 judges whether general facsimile receiving is finished (S77).

If general facsimile receiving is finished (S77: YES), processing proceeds to S74, the line is disconnected and the routine terminates.

In S77, if general facsimile receiving is not finished (S77: NO), processing returns to S76 and general facsimile receiving continues.

In S65, if time measured by the timer started in S63 is not up (S65: NO), processing returns to S64 and the detection of the CNG signal continues.

In S64, if the CNG signal is detected (S64: YES), processing proceeds to S76 because detection of the CNG signal means that automatic sending of facsimile data is then executed in the calling terminal. Processing after general facsimile receiving is then executed.

In S61, if the facsimile terminal equipment is not called (S61: NO), the routine terminates.

In the above F/T mode, even during the conversation in S73, processing can proceed to the message box processing in S78 by a user pressing any of the box specifying keys 23 or pressing any of the dial keys on the side of the calling terminal.

Next, receiving processing in a manual receiving mode will be described. In the manual receiving mode, as shown in FIG. 8, the CPU 1 judges whether the facsimile terminal equipment is called (S81).

If the equipment is called (S81: YES), the CPU 1 rings the calling bell (S82) and judges whether the handset is off hook (S83). That is, the CPU 1 checks whether a user lifts the handset off hook or presses the speaker phone key 42.

If the handset is off hook (S83: YES), the CPU 1 controls the NCU 2 to close a line and receive messages (S84). The CPU 1 then judges whether the start key 33 of the body is pressed (S85). That is, the CPU 1 checks whether the user of the above facsimile terminal equipment presses the start key 33.

If the start key is not pressed (S85: NO), the CPU 1 judges whether the recording key 24 of the body is pressed (S86). That is, the CPU 1 checks whether the recording key 24 is pressed because the user of the facsimile terminal equipment presses the recording key 24 of the body to record the conversation.

If the recording key 24 is not pressed (S86: NO), the CPU 1 judges whether the key 23 for specifying the message box number is pressed (S87). That is, the CPU 1 checks whether the operation to input a message to any of message boxes A to E is executed because if the user of the calling terminal wants to input a message to any of the message boxes A to E during the conversation, the user operates the facsimile terminal equipment to input the message to the message box. That is, the CPU 1 checks whether the private key 29, any of the box specifying keys 23 and the recording key 24 are pressed in order. However, the keys need not be pressed in the above order and may be any predetermined order.

If the key 23 for specifying the message box number is not pressed (S87: NO), the CPU 1 judges whether the DTMF signal for specifying the box number is detected (S88). That is, the CPU 1 checks whether the DTMF signal is input because if the user of the calling terminal wants to input a message to the message box, the DTMF signal corresponding to the pressed dial key is input via the telephone line 21 when any dial key of the calling terminal is pressed to specify the message box number without requesting the user of the facsimile terminal equipment to execute the operation. The box specifying keys 23 (A to E) of the facsimile terminal equipment correspond to each message box, respectively, and these message boxes respectively correspond to the dial keys 1 to 5 of the calling terminal, for example. Therefore, the desired message box is specified by pressing any of the dial keys 1 to 5 on the side of the calling terminal in place of pressing any of the box specifying keys A to E 23. For example, the dial keys of the calling terminal are pressed in the order of [0], [1] and [*] in place of the box specifying key "A" 23.

If the DTMF signal for specifying the box number is not detected (S88: NO), the CPU 1 judges whether a key for requiring general retrieval is pressed (S89). That is, the CPU 1 checks whether an operation to input a message to the general mail box is executed by the user of the facsimile terminal equipment. If the user of the calling terminal wants to input a message to the message box for a specific individual but not to the general mail box, he/she informs the user of the facsimile terminal equipment of the above during the conversation. That is, the CPU 1 checks whether the private key 29 and the recording key 24 are pressed in order. However, the keys need not be pressed in the above order and may be any predetermined order.

If the key for requiring general retrieval is not pressed (S89: NO), the CPU 1 judges whether the DTMF signal for requiring general retrieval is detected (S90). That is, the CPU 1 checks whether the DTMF signal is input because if the user of the calling terminal wants to input a message to the general mail box, the DTMF signal corresponding to the pressed dial key 1-5 is input via the telephone line 21 when any dial key 1-5 of the calling terminal is pressed without requesting the user of the facsimile terminal equipment to execute the operation for the above. The above dial key 1-5 is required to be determined beforehand to differentiate it from the dial key for specifying the message box number.

If the DTMF signal for requiring general retrieval is not detected (S90: NO), the CPU 1 judges whether the handset is on hook (S91). That is, the CPU 1 checks whether the user puts the handset of the body on hook, presses speaker phone key 42 or presses the outside line key 52 of the accessory handset 16.

If the handset is on hook (S91: YES), the CPU 1 controls the NCU 2 to disconnect the line (S92) and then terminates the routine.

In S91, if the handset is not on hook (S91: NO), processing returns to S85 and the conversation continues.

In S90, if the DTMF signal for requiring general retrieval is detected (S91: YES), the CPU 1 starts the reproduction of the contents of general information storage area (S93). That is, the CPU 1 reads voice data stored in the voice data storage area of any general information storage area in the RAM 3. The CODEC 8 then converts the voice data to the analog aural signal. Then the CPU 1 sends the aural signal to the telephone line 21 via the NCU 2. Next, the CPU 1 judges whether the reproduction of the contents of the general information storage area is finished (S94).

If the reproduction of the contents of general information storage area is finished (S94: YES), the CPU 1 outputs a sound for reporting a facsimile message (S95). Specifically, the CPU 1 reads voice data corresponding to the reporting message that facsimile data stored in the response message storage area in the RAM 3 is sent. The CODEC 8 then converts the voice data to the analog aural signal. The CPU 1 then sends the aural signal to the telephone line 21 via the NCU 2. Facsimile receiving is started when the user of the calling terminal presses the start key of the calling terminal.

Next, the CPU 1 reproduces facsimile data in the general mail box (S96). Specifically, the CPU 1 reads facsimile data stored in the facsimile data storage area of any general information storage area corresponding to the general mail box in the RAM 3. The modem 4 then modulates the facsimile data. Then the CPU 1 sends the facsimile signal to the telephone line 21 via the NCU 2. Next, the CPU 1 judges whether the reproduction of facsimile data in the general mail box is finished (S97).

If the reproduction of facsimile data in the general mail box is finished (S97: YES), processing proceeds to S92, the line is disconnected and the routine terminates.

In S97, if the above reproduction is not finished (S97: NO), processing returns to S96 and the reproduction of facsimile data in the general mail box continues.

In S94, if the reproduction of the contents of the general information storage area is not finished (S94: NO), processing returns to S93 and the reproduction of the contents of the general information storage area continues.

In S89, if general retrieval is executed (S89: YES), processing proceeds to S93 and processing after the reproduction of the contents of the general information storage area is executed.

In S88, if the DTMF signal for specifying the box number is detected (S88: YES), the CPU 1 executes message box processing (S98) because the above means the message is addressed to a specific individual. The CPU 1 then terminates the routine. The above message box processing is the same as that shown in FIG. 6.

In S87, if the key for specifying the message box number is pressed (S87: YES), processing proceeds to S98 because the above means the message is addressed to a specific individual. The CPU 1 then executes message box processing.

In S86, if the recording key 24 is pressed (S86: YES), the CPU 1 executes general conversation recording (S99). That is, aural signals input via the telephone line 21 from the calling terminal and aural signals from the microphone of the handset are converted to digital voice data by the CODEC 8 and are stored in the RAM 3. The above voice data is not stored in a personal information storage area or a general information storage area because it is not a message. Instead, the voice data is stored in a separate, predetermined area. Next, the CPU 1 judges whether the handset is put on hook (S100). That is, the CPU 1 checks whether the user puts the handset of the body on hook, presses the speaker phone key 42 or presses the outside line key 52 of the accessory handset 16.

If the handset is put on hook (S100: YES), processing proceeds to S92, the line is disconnected and the routine terminates.

In S100, if the handset is not put on hook (S100: NO), processing returns to S99 and the general conversation recording continues.

In S85, if the start key is pressed (S85: YES), the CPU 1 executes general facsimile receiving (S101) because the above means that facsimile data not addressed to a specific individual is received. Specifically, if memory receiving is set, facsimile data received via the telephone line 21 is stored in the facsimile data storage area in any general information storage area in the RAM 3. If memory receiving is not set, facsimile data received via the telephone line 21 is recorded on recording paper by the recording section 12. Next, the CPU 1 judges whether the general facsimile receiving is finished (S102).

If general facsimile receiving is finished (S102: YES), processing proceeds to S92, the line is disconnected and the routine terminates.

In S102, if general facsimile receiving is not finished (S102: NO), processing returns to S101 and the general facsimile receiving continues.

In S83, if the handset is not off hook (S83: NO), processing returns to S82 and ringing the calling bell continues.

In S81, if the facsimile terminal equipment is not called (S81: NO), the routine terminates.

Next, a conversation in a manual receiving mode using the accessory handset 16 is described. As shown in FIG. 9, the CPU (not shown) of the accessory handset 16 judges whether the facsimile receiving key 60 is pressed (S111). That is, the CPU of the accessory handset checks whether the user of the accessory handset 16 presses the facsimile receiving key 60 because if the user of the calling terminal wants facsimile sending not addressed to a specific individual and requests the user of the accessory handset 16 to enable the facsimile sending during the conversation, the user of the accessory handset 16 presses the facsimile receiving key 60.

If the facsimile receiving key 60 is not pressed (S111: NO), the CPU of the accessory handset 16 judges whether the key for specifying the message box number is pressed (S112). That is, the CPU of the accessory handset checks whether the key for specifying the message box number is pressed because if the user of the calling terminal wants to input a message addressed to a specific individual to the message box and requests the user of the accessory handset 16 to enable the above input during the conversation, the user of the accessory handset 16 presses a predetermined dial key 51 to specify the message box number. The operation of the above dial key 51 is the same as that in case the message box number is specified by the DTMF signal using the calling terminal.

If the key for specifying the message box number is not pressed (S112: NO), the CPU of the accessory handset 16 judges whether the key for requiring general retrieval is pressed (S113). That is, the CPU of the accessory handset checks whether the key for requiring general retrieval is pressed because if the user of the calling terminal wants to extract a message stored in the general mail box and not addressed to a specific individual and requests the user of the accessory handset 16 to enable the extraction of the message during the conversation, the user of the accessory handset 16 presses a predetermined dial key 51. The operation of the dial key 51 is the same as when general retrieval is required by the DTMF signal using the calling terminal.

If the key for requiring general retrieval is not pressed (S113: NO), the CPU of the accessory handset 16 judges whether the hanging-up key 53 is pressed (S114). That is, the CPU of the accessory handset checks whether the hanging-up key is pressed because if the conversation is finished, the user of the accessory handset 16 presses the hanging-up key 53.

If the hanging-up key 53 is pressed (S114: YES), the CPU of the accessory handset 16 sends a code for directing disconnection to the communication section 15 of the body (S115) and terminates the routine. Then, the CPU of the accessory handset disconnects the line.

In S114, if the hanging-up key 53 is not pressed (S114: NO), processing returns to S111 and the above procedure repeats.

In S113, if the key for requiring general retrieval is pressed (S113: YES), the CPU of the accessory handset 16 sends the DTMF signal for requiring general retrieval to the communication section 15 of the body (S116). The CPU of the accessory handset then terminates the routine. Then, the CPU of the accessory handset executes the same operation as in the case where the DTMF signal for requiring general retrieval is input via the telephone line 21.

In S112, if the key for specifying the message box number is pressed (S112: YES), the CPU of the accessory handset 16 sends the DTMF signal for specifying the message box number to the communication section 15 of the body (S117). The CPU of the accessory handset then terminates the routine. Then, the CPU of the accessory handset executes the same operation as in the case where the DTMF signal for specifying the message box number is input via the telephone line 21.

In S111, if the facsimile receiving key 60 is pressed (S111: YES), the CPU 1 of the accessory handset 16 sends a code for directing general facsimile receiving to the communication section 15 of the body (S118). The CPU 1 then terminates the routine. Then, the CPU 1 executes processing for general facsimile receiving.

Next, a line monitoring mode, which is the operation mode of the body when the accessory handset 16 is in the manual receiving mode, will be described. In the line monitoring mode, as shown in FIG. 10, the CPU 1 judges whether a code for directing facsimile receiving is detected (S121). That is, the CPU 1 checks whether the code for directing facsimile receiving from the accessory handset 16 is received by the communication section 15.

If the code for directing facsimile receiving is not detected (S121: NO), the CPU 1 judges whether the DTMF signal for specifying the message box number is detected (S122). That is, the CPU 1 checks whether the DTMF signal for specifying the message box number from the accessory handset 16 is received by the communication section 15 or the DTMF signal for specifying the message box number is input via the telephone line 21.

If the DTMF signal specifying the message box number is not detected (S122: NO), the CPU 1 judges whether the DTMF signal requiring general retrieval is detected (S123). That is, the CPU 1 checks whether the DTMF signal requiring general retrieval from the accessory handset 16 is received by the communication section 15 or the DTMF signal for requiring general retrieval is input via the telephone line 21.

If the DTMF signal requiring general retrieval is not detected (S123: NO), the CPU 1 judges whether the conversation is finished (S124). That is, the CPU 1 checks whether a code for directing disconnection from the accessory handset 16 is received by the communication section 15.

If the conversation is finished (S124: YES), the CPU 1 controls the NCU 2 to disconnect the line (S125) and terminates the routine.

In S124, if the conversation is not finished (S124: NO), processing returns to S121 and the above processing repeats.

In S123, if the DTMF signal requiring general retrieval is detected (S123: YES), the CPU 1 starts the reproduction of the contents of the general information storage area (S126). Specifically, the CPU 1 reads voice data stored in the voice data storage area in any general information storage area in the RAM 3. Then, the CODEC 8 converts the voice data to the analog aural signal. The CPU 1 then sends the aural signal to the telephone line 21 via the NCU 2. Next, the CPU 1 judges whether the reproduction of the contents of the general information storage area is finished (S127).

If the reproduction of the contents of the general information storage area is finished (S127: YES), the CPU 1 outputs a sound for reporting on the facsimile message (S128). Specifically, the CPU 1 reads voice data corresponding to a reporting message that facsimile data stored in the response message storage area in the RAM 3 is sent. Then, the CODEC 8 converts the voice data to the analog aural signal. The CPU 1 then sends the aural signal to the telephone line 21 via the NCU 2. Then, when the user of the calling terminal presses the start key of the calling terminal, facsimile receiving starts.

Next, the CPU 1 reproduces facsimile data in the general mail box (S129). Specifically, the modem 4 modulates facsimile data stored in the facsimile data storage area of the general information storage area corresponding to the general mail box in the RAM 3. Then, the CPU 1 sends the facsimile signal to the telephone line 21 via the NCU 2. Next, the CPU 1 judges whether the reproduction of facsimile data in the general mail box is finished (S130).

If the reproduction of the facsimile data in the general mail box is finished (S130: YES), processing proceeds to S125, the line is disconnected and the routine terminates.

In S130, if the reproduction of the facsimile data in the general mail box is not finished (S130: NO), processing returns to S129 and the reproduction of the facsimile data in the general mail box continues.

In S127, if the reproduction of the contents of the general information storage area is not finished (S127: NO), processing returns to S126 and the reproduction of the contents of the general information storage area continues.

In S122, if the DTMF signal for specifying the message box number is detected (S122: YES), the CPU 1 executes message box processing (S131) and terminates the routine. The above message box processing is he same as that shown in FIG. 6.

In S121, if the code for directing facsimile receiving is detected (S121: YES), the CPU 1 executes general facsimile receiving (S132). Specifically, if memory receiving is set, facsimile data received via the telephone line 21 is stored in the facsimile data storage area of any general information storage area in the RAM 3. If memory receiving is not set, facsimile data received via the telephone line 21 is recorded on recording paper by the recording section 12. Next, the CPU 1 judges whether general facsimile receiving is finished (S133).

If general facsimile receiving is finished (S133: YES), processing proceeds to S125, the line is disconnected and the routine terminates.

In S133, if general facsimile receiving is not finished (S133: NO), processing returns to S132 and general facsimile receiving continues.

Next, a standby mode, which is an operation mode of the body when no sending, receiving and copying are executed, and the operation based on a key operation from the standby mode, will be described. In the standby mode, as shown in FIG. 11, the CPU 1 judges whether the function key 28 is pressed (S140). That is, because various setting and registration events, except matters related to the message box, are made in the RAM 3 and the EEPROM 6 of the above facsimile terminal equipment, if a user presses the function key 28, the CPU 1 checks which key is pressed.

If the function key 28 is not pressed (S140: NO), the CPU 1 judges whether any of the box specifying keys 23 are pressed (S141). That is, the box specifying keys 23 are used not only for specifying the message box number but also for a touch tone dial. If the user wants to call using the touch tone dial, the user presses a desired box specifying key 23 and the CPU 1 checks that the box specifying key is pressed.

If no box specifying key 23 is pressed (S141: NO), the CPU 1 judges whether the private key 29 is pressed (S142). That is, the user presses the private key 29 for registration related to the message box, the display of a telephone directory, access and other functions.

If the private key 29 is not pressed (S142: NO), the CPU 1 terminates the routine. In the standby mode, the CPU 1 waits ready for detecting that the function key 28, any of the box specifying keys 23 or the private key 29 is pressed.

In S142, if the private key 29 is pressed (S142: YES), the CPU 1 judges whether any of the dial keys 22 are pressed (S143). That is, if the user wants to retrieve the whole classified telephone directory of every specific individual corresponding to the message box, the user presses any of the dial keys 22 after the private key 29. The CPU 1 checks this event. The telephone directory in this embodiment is a set of telephone numbers stored in the EEPROM 6 by the operation for registration of the user. The name of a destination and a serial number representing a position in the telephone directory are stored in the EEPROM 6 with the name of the destination related to each telephone number. A group name can also be registered in the telephone directory with the group name corresponding to each telephone number. Then, a private telephone directory including only telephone numbers classified under the same group name can be utilized. Then, if a private telephone directory is used, the private telephone directory can be used as a telephone directory in which only telephone numbers that belong to a specific group are registered.

In S143, if none of the dial keys 22 are pressed (S143: NO), the CPU 1 judges whether the function key 28 is pressed (S144). That is, the CPU 1 checks if a user executes various setting and registration events related the message box by pressing the function key 28 after the private key 29.

In S144, if the function key 28 is not pressed (S144: NO), the CPU 1 judges whether any of the box specifying keys 23 are pressed (S145). That is, the CPU 1 checks if the user wants to utilize a private telephone directory and wants to access the message box by pressing a desired box specifying key 23 after the private key 29.

In S145, if no box specifying key 23 is pressed (S145: NO), the CPU 1 terminates the routine. That is, if none of the box specifying keys 23 are pressed and the function key 28 is not pressed in a predetermined time after the private key 29 is pressed, processing to be executed cannot be specified, and the CPU 1 terminates the routine.

In S145, if any of the box specifying keys 23 are pressed (S145: YES), the CPU 1 executes dialing utilizing a private telephone directory and private processing for accessing a message box (S146). The CPU 1 then terminates the routine. The above private processing will be described in detail later.

In S144, if the function key 28 is pressed (S144: YES), the CPU 1 judges whether any of the box specifying keys 23 are pressed (S147). That is, the CPU 1 checks if registration related to a message box specified by the box specify key 23 is made by the user pressing the private key 29, the function key 28 and any of the box specifying keys 23 in order.

If any of the box specifying keys 23 is pressed (S147: YES), the CPU 1 executes various registration events based upon an operation for registration by the user (S148) and terminates the routine. That is, the name of a group and a response message, for example, are stored in the RAM 3 or in the EEPROM 6 according to various key operations by the user.

In S147, if no box specifying key 23 is pressed (S147: NO), the CPU 1 terminates the routine. That is, if no box specifying key 23 is pressed in the predetermined time after the function key 28 is pressed, the CPU 1 judges that the user does not want registration related the message box. The CPU 1 and terminates the routine.

In S143, if any of the dial keys 22 are pressed (S143: YES), the CPU 1 judges whether the start key 33 is pressed (S149). That is, the CPU 1 checks whether the start key 33 to dial a telephone number specified by the dial key 22 is pressed after the private key 29 and any of the dial keys are pressed.

If the start key 33 is pressed (S149: YES), the telephone number is dialed (S150) and the routine terminates. That is, when the user inputs the desired two digits of a serial number in a telephone directory by pressing the dial keys 22, the name or the telephone number of a destination corresponding to the serial number is displayed on the LCD 45 display screen. The user then presses the start key 33 if the destination is the desired one. Then, the telephone number of the destination displayed on the LCD 45 display screen is automatically called.

In S149, if the start key 33 is not pressed (S149: NO), the CPU 1 terminates the routine. That is, if the start key 33 is not pressed in the predetermined time after any of the dial keys 22 are pressed, the CPU 1 judges that the user does not want a call utilizing an abbreviated dial in a private telephone directory. The CPU 1 then terminates the routine.

In S141, if any of the box specifying keys 23 are pressed (S143: YES), the CPU 1 judges whether the handset is put on hook (S151) because the above means that the user wants to dial the telephone number corresponding to the box specifying key 23.

If the handset is put on hook (S151: YES), the CPU 1 judges whether the start key 33 is pressed (S152). That is, if the user presses any of the box specifying keys 23, the name of the destination of the touch tone dial corresponding to the box specifying key 23 is displayed on the LCD 45 display screen. If the desired destination is correct, the user presses the start key 33 with the handset on hook.

If the start key 33 is pressed (S152: YES), the CPU 1 dials the telephone number specified by the box specified key 23 (S153) and terminates the routine.

In S152, if the start key 33 is not pressed (S152: NO), the CPU 1 terminates the routine without dialing. That is, if the start key 33 is not pressed in the predetermined time after any of the box specifying keys 23 are pressed, the CPU 1 judges that the user does not want the call by the touch tone dial. The CPU 1 then terminates the routine.

In S151, if the handset is not put on hook (S151: NO), the line is already closed, and processing proceeds to S153 without waiting for the start key 33 to be pressed. The telephone number is then dialed.

In S140, if the function key 28 is pressed (S140: YES), the CPU 1 judges that the user wants various setting and registration events, except matters related to the message box. The CPU 1 then executes setting and registration according to various key operations by the user (S154). The CPU 1 then terminates the routine.

Next, the details of private processing executed in S146 will be described. In private processing, as shown in FIG. 12, the CPU 1 judges whether correct personal identification numbers are input (S160). Specifically, the CPU 1 checks whether personal identification numbers corresponding to the message box specified by any of the box specifying keys 23 are input by the user pressing some of the dial keys 22. That is, the CPU 1 checks personal identification numbers to prevent a person who does not know the personal identification numbers of the message box from using the private telephone directory or from accessing the message box.

If correct personal identification numbers are input (S160: YES), the CPU 1 judges whether the erase key 25 is pressed (S161). That is, the CPU 1 check if the user wants to erase a message stored in the message box. The user indicates an erase operation by pressing the erase key 25.

If the erase key 25 is not pressed (S161: NO), the CPU 1 judges whether the reproduction key 26 is pressed (S162). That is, the CPU 1 checks if the user wants to reproduce a message stored in the message box by pressing the reproduction key 26.

If the reproduction key 26 is not pressed (S162: NO), the CPU 1 judges whether the recording key 24 is pressed (S163). That is, the CPU 1 checks if the user wants to store a message in the message box by pressing the recording key 24.

If the recording key 24 is not pressed (S163: NO), the CPU 1 judges whether some of the dial keys 22 are pressed (S164). That is, the CPU 1 checks if the user wants to call by an abbreviated dial utilizing a private telephone directory, by pressing one or more of the dial keys 22.

If no dial key 22 is pressed (S164: NO), the CPU 1 judges whether any of the box specifying keys 23 are pressed (S165). That is, the CPU 1 checks if the user wants to retrieve a private telephone directory and make a call, by pressing any of the box specifying keys 23 or the left or the right scroll keys 36 or 38.

If no box specifying keys 23 are pressed (S165: NO), the CPU 1 judges whether the left or the right scroll keys 36 or 38 are pressed (S166). That is, the CPU 1 checks if the user wants to retrieve a private telephone directory and make a call, by determining if the under presses any of the box specifying keys 23 or the left or the right scroll keys 36 or 38.

If the left or the right scroll keys 36 or 38 are not pressed (S166: NO), the CPU 1 terminates the routine. That is, if no key operation is executed in predetermined time after correct personal identification numbers are input, the CPU 1 judges that the user does not want the use of the private telephone directory and access to the message box. The CPU 1 then terminates the routine.

In S166, if the left scroll key 36 or the right scroll key 38 is pressed (S166: YES), the CPU 1 judges whether the start key 33 is pressed (S167). That is, as the name of a sending destination displayed on the LCD 45 display screen in a private telephone directory is switched in order when the user presses the left scroll key 36 or the right scroll key 38. The CPU 1 then checks if the user presses the start key 33 to indicate when the name of the desired sending destination is displayed.

If the start key 33 is pressed (S167: YES), the CPU 1 dials the telephone number corresponding to the sending destination displayed on the display screen of the LCD 45 (S168). The CPU 1 then terminates the routine.

In S167, if the start key 33 is not pressed (S167: NO), the CPU 1 terminates the routine without dialing. That is, if the start key 33 is not pressed in the predetermined time after the left scroll key 36 or the right scroll key 38 is pressed, the CPU 1 judges that the user does not want the call by the retrieval of the private telephone directory. The CPU 1 then terminates the routine.

In S165, if any of the box specifying keys 23 are pressed (S165: YES), processing proceeds to S167 and processing after the CPU 1 judges whether the start key 33 is pressed is executed. That is, when the name of a sending destination displayed on the LCD 45 display screen in a private telephone directory is switched in order every time the user presses a desired box specifying key 23, the CPU 1 executes the same processing as when the left or right scroll keys 36 or 38 are pressed.

In S164, if one or more of the dial keys 22 are pressed (S164: YES), the CPU 1 judges whether the handset is put on hook (S169).

If the handset is put on hook (S169: YES), processing proceeds to S167. If the handset is not put on hook (S169: NO), the start key 33 is not required to be pressed, and processing proceeds to S168.

In S163, if the recording key 24 is pressed (S163: YES), the CPU 1 judges whether the handset is put on hook (S170).

If the handset is put on hook (S170: YES), the CPU 1 records the data of the voice of the user in the message box (S171). If the handset is not put on hook (S170: NO), the CPU 1 records the data of the voice of a party and the user in the message box (S172) and terminates the routine. In the above recording of the user, voice data the voice of the user is input to the microphone, provided differently from the handset, and is stored in the message box. In the above recording of the voice data of a party and a user, the voice of the party is input via the telephone line 21 and the voice of the user is stored in the message box.

If the handset is put on hook (S170: YES), the CPU 1 records the data of the voice of the user in the message box (S171), and if the handset is not put on hook (S170: NO), the CPU 1 records the data of the voice of a party and the user in the message box (S172) and terminates the routine. The above recording of the user's voice means storing the data of the voice of the user input to the microphone provided differently from the handset in the message box. The recording of the party's voice and the user's voice means storing the data of the voice of the party input via the telephone line 21 and the voice of the user in the message box.

In S162, if the reproduction key 26 is pressed (S162: YES), the CPU 1 reproduces the voice message stored in the message box (S173). The CPU 1 then reproduces the facsimile message stored in the message box (S174) and terminates the routine. When the voice message is reproduced, the handset speaker is used if the handset is off hook. A speaker provided separately from the handset is used if the handset is put on hook. A facsimile message is reproduced by printing an image based on facsimile data stored in the message box on recording paper by the recording section 12.

In S161, if the erase key 25 is pressed (S161: YES), the CPU 1 erases the message stored in the message box (S175). The CPU 1 then terminates the routine.

In S160, if correct personal identification numbers are not input (S160: NO), the CPU 1 terminates the routine.

"A message box" described in the procedure of the above private processing shown in FIG. 12 means the message box specified when the user presses any of the box specifying keys 23.
